OpManager is not something that we ship Nagios XI with...java process is taking so much CPU.

Sl Jul24 1158:33 /opt/ManageEngine/OpManager/bin/../jre/bin/java -cp /opt/ManageEngine/OpManager/bin/../classes/AdventNImportant: Nagios Enterprises highly recommends and will only support installing Nagios XI on a newly installed, "clean" system. Attempting to install Nagios XI on a pre-existing system with other applications already installed can cause the Nagios XI installation process to fail, critical system components and settings (e.g. database servers) to be modified in a way that negatively affects other applications, and previously installed applications to be automatically upgraded or removed. While installing XI on a system with other applications is possible, it is not recommended due to the possible interactions and complexity of multiple components that are required for Nagios XI to function. If you choose to ignore these warnings, you do so at your own risk.
You need to fix the high load issue first by removing the "problem" applications, adding more hardware resources, etc. When your load exceeds the "load_threshold" value that is set up in the "/usr/local/nagios/etc/pnp/npcd.cfg" file, the npcd stops running, and your graphs disappear. You can increase the "default" value of "10" if you have enough resources (dual core = 20, quad core = 40, etc.).
Run the following commands and show the output:
